Question

我在我的代码

上收到此错误消息

system.data.sqlclient.sqlexception＆nbspchar＆＃39;
附近的语法不正确
必须声明标量变量@Flag

这是我到目前为止的代码：

try
{
    if (dbConn.State == ConnectionState.Closed)
    {
        dbConn.Open();
    }

    dbCmd = new SqlCommand("INSERT INTO Shop(ShopID,ShopName,Location,Size,CostPerMeter,[TenantID(FK)],Flag)" +
                    "VALUES(@ShopID,@ShopName,@Location,@Size,@CostPerMeter,@[TenantID(FK)],@Flag);", dbConn);

    dbCmd.Parameters.AddWithValue("@ShopID", txtPrimary.Text);
    dbCmd.Parameters.AddWithValue("@ShopName", txtShopName.Text);
    dbCmd.Parameters.AddWithValue("@Location", txtLoc.Text);
    dbCmd.Parameters.AddWithValue("@Size", txtSize.Text);
    dbCmd.Parameters.AddWithValue("@CostPerMeter", txtCPM.Text);
    dbCmd.Parameters.AddWithValue("@[TenantID(FK)]", txtTenID.Text);

    dbCmd.ExecuteNonQuery();

    ds.Tables["Shop"].Rows.Add(new object[] { txtPrimary.Text, txtShopName.Text, txtLoc.Text, txtSize.Text, txtCPM.Text, txtTenID.Text, });

    txtPrimary.Clear();
    txtShopName.Clear();
    txtLoc.Clear();
    txtSize.Clear();
    txtCPM.Clear();
    txtTenID.Clear();
}
catch (Exception ex)
{
    MessageBox.Show(ex.ToString());
}

您在查询中引用@Flag，但绝不给它相应的参数值。只需为@Flag添加参数值：

dbCmd.Parameters.AddWithValue("@Flag", true); // set however appropriate

我在＆nbspchar＆＃39; nvarchar＆＃39;附近得到了system.data.sqlclient.sqlexception错误的语法。错误信息
